Commercial heating repair before the cold snap hits

Commercial heating repair

The first cold week of the year is when heating problems show up, and most of them are small parts that failed while the unit sat idle. We diagnose and fix on the first visit when we can. What we see most:

• Igniters, flame sensors, and ignition control failures
• Gas valves and gas pressure problems
• Cracked heat exchangers
• Inducer and blower motor failures
• Limit switch and rollout trips
• Heat pump defrost and reversing valve faults
• Electric heat strips and sequencers
• Thermostat and zone control faults

Rooftop units and packaged heating

Most commercial buildings in the metro heat with gas sections in rooftop package units. We service the heat side of every RTU brand, and when the unit is done we replace it with a crane-set changeout scheduled around your hours. If the building has a separate furnace or air handler with a hot water or electric coil, we work on that too.

Fall start-up and preventive maintenance

A fall visit is the cheapest heating repair there is. We fire every unit, check it under load, and fix the small stuff before it strands you in January. Heating maintenance is part of our commercial preventive maintenance programs, or we can do it as a one-time start-up.

• Fire every stage and verify operation
• Check gas pressure and combustion
• Inspect heat exchangers
• Clean burners and flame sensors
• Filters, belts, and motors
• Test limits and safeties
• Written report with anything that needs attention

Airflow and duct

A furnace or heat section is only as good as the duct behind it. Long runs, undersized returns, and rooms that were added after the system was designed leave one end of the building hot and the other cold. We run our own sheet metal shop, so we can rebuild a plenum, add a return, or rework a trunk line without waiting on someone else's fabrication schedule.

Kitchens, schools, and high-occupancy buildings

Kitchens are a heating problem as much as a cooling one. Make-up air units have to heat the air they bring in, or the cook line is freezing every time the hood runs. We work on kitchen hood and make-up air systems for schools and restaurants across the metro.

Schools, churches, and other buildings with a schedule get the same treatment: we set the equipment up for how the building is actually used, not for 24-hour occupancy.

Repair, replace, or retrofit

Some heating equipment is worth fixing. Some is not. A cracked heat exchanger on a 20-year-old unit is a replacement conversation. A failed igniter on a 6-year-old unit is a repair. We give you the honest version, and where a retrofit or efficiency upgrade makes sense, we lay out what it would save.
